Both in dressed in short sundresses, Christina was snapped chatting away with guests at the party while holding some gifts. Meanwhile, cameras caught up with mommy-to-be January walking the beach outside her Malibu, Calif. retreat.

January announced in April that she was pregnant and, according to her rep, was “really looking forward to this new chapter in her life as a single mom.” Still no word on who her baby’s daddy is but The X Men: First Class actress was linked to Bobby Flay and Jeremy Piven earlier this year after ending a seven month relationship with SNL‘s Jason Sudeikis back in January.

Since announcing her pregnancy, we’ve seen January out and about a slew of times, typically heading to yoga class. Be sure to follow Celebuzz on Twitter, Facebook and Tumblr for more baby bump news and pics!
